Abstract
Low-profile thermally stable lubricants for data storage devices are provided based on multi-dentate molecular designs. One such lubricant comprises perfluoroalkyl ether segments, a divalent linking segment, and anchoring functional groups attachable to, or engageable with, a protective overcoat of a magnetic recording medium. The lubricants can be used in conjunction with a magnetic recording medium and/or a magnetic data storage system.
